On what date was Unorthodox Jukebox released?

Unorthodox Jukebox was released on December 7, 2012. It was Bruno Mars's second studio album, following his 2010 debut Doo-Wops & Hooligans, and Atlantic Records issued it after Mars had spent about a year developing the project.

The album was briefly made available to hear in full before its official release, helping build anticipation around a record that mixed pop, R&B, rock, funk, soul, reggae, and disco. Its lead single, "Locked Out of Heaven," had already arrived on October 1, 2012.

A common mix-up comes from regional release dates. December 7 was used in several markets, while the United States and Canada received the album on December 11, and Japan followed on December 12. The earlier or later dates therefore do not replace the album's commonly cited release date.

The album later produced major singles including "When I Was Your Man," "Treasure," and "Gorilla," and it was promoted through Mars's Moonshine Jungle Tour in 2013 and 2014.
